Pony Pal Trail is special to all the Pony Pals. The trail connects Pam's backyard to the pony paddock Anna and Lulu share. The shortcut lets the girls see each other and their ponies all the time.
But now everything has changed. New neighbors have built a sheep pen that blocks part of the trail. What will the Pony Pals do if they can't use the trail? Will Pam be the left out Pony Pal?
